Hi all, I am very interested in chemical PE but had a few questions. The main component seems to be PGE-1, could something like this be used if reconstituted in sterile PBS and filtered through a 0.22um filter in a BSC? http://www.sigmaaldrich.com/catalog/product/sigma/p5515?lang=en®ion=US From my readings, starting at a smaller volume and going up from roughly 2.5ug per injection sounds like the safe route. What are the smallest and highest volumes you can safely inject into the CC? I was thinking of making a stock solution where I wouldn't have to perform any further dilutions, is this possible? Also, is there any way to counteract the erection besides an ER visit if you near the 5~6 hours? I've read reports of Sudafed being somewhat effective. Thanks!
